T 0 all whom it may concern:

Be it known that I, Voariorr Pro, a citizen of the Czecho-Slovak Republic, residing in Prague-Vinohrady, Bohemia, have invented certain new and useful Improvements 'in Safety Pins, for which I have filed applications in Germany, filed July 31, 1916, patented Oct. 24, 1916, No. 300,242; in Spain, filed Sept. 19, 1919, patented Jan. 20, 1920, No. 71,418; in Denmark, filed Sept, 19 1919, patented Aug. 25, 1920, No. 26,57 5, of which the following is a specification.

This invention relates to safety pins, in which the pointed end,'the spring and the stationary member are made of a single piece of wire and in which a guard is provided for the point of the pin and for supporting the inner end of the stationary member of the pin. My improvements especially relate to the particular construction of the guard, and consist in a novel way of forming the guard with recesses or slots, through which Figure 3 is a perspective view, on an enlarged scale, of the guard, showing it associated with the stationary member of the.

pin and the pointed member.

Figure 4 shows a sectionon the line 44' of Fig. 1.

The stationary member A, the pointed;

member B and the coiled wire spring C may be of usual construction. The guard D is, in general, of well known type, the end a of the stationary member being fixed therein while the pointed end 6 of the pointed memher is adapted to move in and out of the guard.

As indicated most clearly in Figure 4, the inner end of the stationary-member is fixed in the guard by forming a crescent-shaped depression a in the guard which forms a similarly shaped rib.

As most clearly shown in Figure 3 the guard is made of sheet metal closed at its end and at the sides, one side d being adapted to receive the end of the stationar her A. The bottom m of the guar is flat made in the tongue or that part of the mem- . or straight and is formed with a slot n which Specification of Letters Patent. I Patented ltiay 9, 1922. A

towards the outer end thereof, being slightly v inclined from'the middle longitudinal axis towards the opposite side of the guard. The upper side of the guard is formed with a slot 0 which extends inward from the inner edge of the guard towards the outer end thereof. This slot is relatively wide at its entrance,

is narrow in its middle portion and is considerably enlarged atits inner end-r. s indicates a tongue on one side of the slot which extends over the slot n to afford a guide for the pointed end of the pin. A

closed. WVhen the pin is opened it will nat urally pass out of the slot n and the pin may pin through the same slot. The pin may also be opened by passing its pointed end out through the slot 0, over the guide 8, and in closing the pin it is most convenient to place the'pointed end on top ofthe tongue 8 and allowthe pin to find its seat in the guard.

be closed by returning the pointed end of the r i It will be observed that the guard does not 7' entirely or closely surround the member A and that no shoulders or obstructions are ard over which the pointed end of the pins ides,

the member A being held firmly in place by the crescent-shaped depression and rib" or. The recesses or slots n overlap i. e., they are inclined in opposite directions so that the pointed end of the pin may be removed from either side of the guard most easily.- It will be observed, also, that the tongue 8 is inclined from the top of the guard inwards and downwards and this affords a smooth and easy path for the closing the pin. 7 I claim as my invention -1. A safety pin, comprising a stationary member, a movable pointed member conpoint in either-opening or nected by a coil, and a sheet metal guard,

one side of which is formed with a diagonal I slot and is flat and straight between the stationary and pointed members and the opposite side of which is formed with a diago- 'diaglonally inwards toward the'opposite side of t e guard across the slot therein.

2. A safety pin comprising a Stationary member, a pointed member, and a guard to which the end of the stationary member is secured and which is provided on oneside 10 to form a guide forthe pointed end of the pin, the outer end of saidtongue being dis posed between the slot on one side of the guard, and the fixed member of the pin, while the inner portion of the tongue extends directly without bend from the adjacent portion of the stationary member toward the pointed member.

In testimony whereof, I have hereunto subscribed my name.
